Hello,
I would have to double check BUT I believe this is fixed in later 2.4.x
kernels as well. If you don't want to go through the hassle of 2.6
(although it really is a nice kernel) then upgrade to 2.4.26.
Sincerely,

I believe it was more like the kernel was tuned to make it less common,
but certain things can still trigger it. I know the problem was still
there in the 2.4.24 on the last server I was playing with, but it was a
lot less of a problem than it had been under 2.4.9 on an earlier machine

A sane kernel should drop disk buff
The problems still remains...
I've tried to change shmax to 128 mb (i've got 2 GB of ram),
then the others parameter are set as follow:
shared_buffers = 8096# 2*max_connections, min 16
max_fsm_relations = 500# min 10, fsm is free space map
max_fsm_pages = 15000 # min 1000, fsm is
We actually found that in the 2.4-20 kernel for RedHat there was a known
issue that was causing cached memory to not be reused and our box
started to swap also.

This may be what you are experiencing if your using the same kernel.

If you really think this is true, there should be a process that is
holding on to the memory. Use 'ps' to find tha
